Abstract

In the Netherlands, 160 farms were surveyed for fascioliasis by ELISA in Nov. 1983. The sensitivity of the test was estimated at 85% and the specificity at 92%. At the threshold of positivity ≥ 5.0 ETC (=ELISA titre count where 1 corresponds to a titre of 1:20 and a 2 to 1:40 etc.), 14% of the...

Abstract

Liveweight of calves on 89 dairy farms in the Netherlands was measured at the end of the grazing season and related per herd to the level of exposure to nematode infection during the grazing season. There were significant between-herd variations in antibody titres against Ostertagia spp., Cooperia ...

Abstract

Liveweight of calves on 86 dairy farms in the Netherlands was measured at the end of the grazing season and related per herd to the level of exposure to nematode infection estimated in October and December. There were significant between-herd variations in all the serological infection parameters...

Abstract

Growth performance of calves was estimated by means of heart girth measurements on 48 farms during winter housing (from December to the end of March) in the Netherlands. Level of exposure to nematode infection was measured by antibody titres, pepsinogen values, and faecal examinations. Ostertagia,...

Abstract

Antibody titres against Ostertagia spp., Cooperia spp. and Dictyocaulus viviparus as well as pepsinogen values, reflecting exposure to nematode infection, differed significantly among herds of second-year cattle on 87 farms in the Netherlands. Faecal examinations revealed that gastrointestinal...

Abstract

Growth performance of calves was assessed on 32 farms during winter housing in the Netherlands. Nematode infection was measured by antibody titres, pepsinogen values, and faecal examinations. Ostertagia, Cooperia, Trichostrongylus, Oesophagostomum and Bunostomum were identified. Half of each herd...

Abstract

The effect of nematode infections on growth performance during winter housing and on first lactation yield was investigated in heifers on 69 farms in the Netherlands from November 1986-April 1987. Half of each herd (mean 10 animals/herd) was treated with albendazole after housing, which resulted in ...
